Professor Penrose contends in that report that Muggles notice much more of what happens in the wizarding community than is generally believed. For example, entries into the Annual International Wizard Gardening Competition’s Contorting Cereals competition have been spotted by Muggles, who call them “crop circles”. The report also discusses the fact that Muggles have spotted escaped Quaffles (labelling them UFOs) as well as the ongoing problem of how to hide the kelpie in Loch Ness from Muggle notice (DP1).
